IXCY10M90S

Current Regulation/Management Overview

The IXCY10M90S is a single die Schottky rectifier manufactured by Littelfuse (IXYS). It features a maximum average forward rectified current of 3A and a repetitive peak reverse voltage of 100V. The device is housed in a TO-252AA (D-PAK) surface mount package with three pins. It operates within a junction temperature range of -55°C to +150°C and utilizes matte tin terminals.

Current Regulation/Management Feature Summary

• Schottky barrier construction for low forward voltage drop
• Single die design for efficient power rectification
• Surface mount compatibility via TO-252AA package

Current Regulation/Management Applications

• DC-DC converter output rectification
• Free-wheeling diode applications in power supplies
• General purpose rectification in consumer electronics

Current Regulation/Management Procurement Notes

Verify the manufacturer designation as Littelfuse or IXYS, as both entities are associated with this component lineage. Confirm the specific suffix indicates the standard tube packaging variant rather than tape-and-reel options if bulk handling is required. Ensure the TO-252AA package type matches the target PCB footprint requirements.

Current Regulation/Management Selection Notes

Select this component when a 3A continuous current rating and 100V blocking capability are required in a compact surface mount form factor. The TO-252AA package offers thermal performance advantages over smaller SMD packages while maintaining board space efficiency compared to through-hole alternatives. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature limits.

Current Regulation/Management Part Context

This part belongs to the IXYS Schottky rectifier family, now integrated into the Littelfuse portfolio. These devices are designed for high-efficiency power conversion applications where low forward voltage drop is critical for minimizing power loss and heat generation in compact electronic systems.
